<rdar://problem/7696607> Links do not respect -webkit-user-drag: none
​https://bugs.webkit.org/show_bug.cgi?id=35475

Reviewed by Maciej Stachowiak.

WebCore:

Test: fast/css/user-drag-none.html

• page/DragController.cpp:

(WebCore::DragController::mayStartDragAtEventLocation): Added a node
parameter. The image drag check is done against the node, rather than
than against the hit test result. This prevents a non-draggable image
with an auto-draggable ancestor from being dragged alone. The link drag
check now ignores links that are -webkit-user-drag: none.

• page/DragController.h:
• page/EventHandler.cpp:

(WebCore::EventHandler::shouldDragAutoNode): Pass the current node
to mayStartDragAtEventLocation().

LayoutTests:

• fast/css/user-drag-none-expected.txt: Added.
• fast/css/user-drag-none.html: Added.

Location:

trunk
